This invention relates to an apparatus for viewing pictures with the illusion of relief, and its object is to provide means which will be capable of apparently projectingf two givenpictures'upon each other to accomplish the object.

It will be understood by those skilled in .the art .that many attempts have been made to show plain pictures in relief but, of course,

the only thing that can be done with a plainplcture in this line is to. deceive the eye and give theillusion of relief instead of actually showing 'any' relief.

In the present instance two series of pictures are used, and the viewing apparatus is receive impressions fromiboth; p1ctures whlle brmgmg them; to a common.

arranged to position and thereby give the eye the illusion of relief.

' Other objects of the invention will appear asthe'descri tion p oceeds. An'embodlment o theinv'ention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that theremayibe modifications thereof.
